Draining Waste Water
Waste water passes from your drain system to the sanitary sewer system through lateral sewer lines from your home or business.
A total of 263 miles of sewer main carries waste water from homes and businesses in Coon Rapids. Trees planted on top of or near your sewer line can cause potential damage and blockage when roots grow downward and penetrate the sewer piping. It is best to keep newly planted trees away from areas known to contain your sewer system piping.
Sewer mains carry waste water, by gravity, to lift stations located throughout Coon Rapids where the waste water is collected then lifted or pumped into larger sewer lines. These lift stations are inspected daily for proper operation. The Utilities Division maintains 16 sewer lift stations throughout the city.
Waste Water Treatment Process
Waste water eventually ends up at the Metropolitan Waste Water Treatment Plant in St. Paul where it is filtered and returned to the Mississippi River.
The Metropolitan Waste Water Treatment Plant, located on the Mississippi River in St. Paul, is the largest waste water treatment facility in Minnesota. When it opened in 1938, it was the 1st plant in a metropolitan area on the Mississippi River. Today it is among the nation's largest, averaging 215 million gallons of waste water every day from 62 communities (including a population of 1.8 million people) and 800 industries.
